PUMP.

SPECIFICATION forming part of Letters Patent No. 319,5'7, dated June 9, 1885.

Application filed March 31, 1884. (No model.)

To aZZ whom it may concern:

Be it known that I, GHARLEs H. BENNETT, of Blossburg, Tioga county, Pennsylvania, have invented a new and Improved Pump, of which the following is a full, clear, and exact description.

This invention relates to certain new and useful improvements in that class of pumps in which the piston is reciprocated vertically by the stand-pipe through which the water rises.

The invention consists in the construction and arrangement of parts, as will be hereinafter fully described and claimed.

Reference is to be had to accompanying drawings, forming part of this specificatiomin which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a longitudinal sectional elevation of my improved pump,parts being broken out. Fig. 2 is a plan view of the under side of the piston and sectional plan view of the cylinder.

The cylinder A is open at the top, and in the cylinder the piston 13 works, which consists of a disk provided in its rim with an annular groove, in which grooved rim a packingstrip or band, 0, of rubber or leather, is held by a cord or wire, D, passed around it and the piston, the edges of the said strip projecting from the top and bottom surfaces of the pis-' ton.

A11 upright pipe, E,has its lower end screwed into the center of the piston, and its upper end, which is above ground, is bent to form a goose neck, E.

To the upper part of the pipe E a lever, F, is pivoted, the end-of which is pivoted to a standard, G, projecting above the platform H of the well or cistern, the lower end of said standard being secured in a casing or pocket, J, on the side of the cylinder, which standard holds the cylinder in place and stiffens and strengthens the pump.

The pistonBis provided with two openings, K, and to the bottom of the piston two valves, L and M, are hinged, which are adapted to swing against the bottom of the piston and close the openings K.

The valve L is provided on its inner edge with a wing, L, adapted to close the lower end of the pipe E, the valve L and the wing L being bent in such a manner that when the wing L closes the lower end of the pipe E the corresponding opening, K,in the piston will be open.

If the piston and the pipe are forced downward, the valves L and M close the openings K, and the water is forced into and up through the bottom of the pipe E.

If the pipe E and the piston 18 are raised upward, the valves LM drop, and the wing L closes the lower end of the pipe E, keeping the water in the pipe E for the time being.

If the pump is not operated, the water in the pipe E forces down the wing L and flows out, and thus the water in the pipe E cannot freeze.

The pump is very simple in construction, can be operated easily, and is not apt to get out of order.

Having thus described my invention,I claim as new, and desire to secure by Letters Patent- 1. The combination, with pipe E and its operating mechanism, of the piston 13, having a central aperture through which the lower end of the pipe passes, avalve on said piston opening downward at the upstroke, and a valve at the base of the pipe E connected with the piston-valve and closing on the upstroke, and the cylinder A, open at its upper end, substantially as described, whereby when the pipe and piston are forced down the piston-valve will close and the pipe-valve will open to allow water to pass into said pipe, and when raised the piston-valve will open and the pipe- 9 valve close to retain the water.

2. In a pump, the combination, with the cylinder A, the piston B, and the pipe E, secured on the piston, of a hinged valve provided with a wing for closing the lower end of the pipe E, substantially as herein shown and described.
